I've been to the 2nd Ave location a million times but this was my first time uptown. I was really surprised by how different the two locations are. The East Village/2nd Ave location really promotes being veg/vegan and has a really cool, young crowd. The uptown location is full of middle class moms pushing strollers and they barely mention they're veg.
The pizza signs say the soy cheese contains casein but the manager told me they JUST started using Follow Your Heart (vegan) cheese but haven't updated the signs yet. This location doesn't have nearly as many vegan options as the 2nd Ave location and they only say "vegan" in small letters. The menu here also seems to be much larger.
I had the Naturale pizza, which had egggplant, red pepper, and spinach. I thought it was a bit dry and I didn't like the eggplant. I was disappointed that there was only one other vegan option and since it was full of mushrooms, I didn't get it.
